what link can i use to direct people to change their preferences?

{{subscriber_preferences_url}}

Thanks! I'm also trying to autofill in the preferences of existing subs (so that I can eventually use proper segments once I give them the option to change their preferences on their own). Any ideas how to do so?

yes, you can run the automation, use update subscription and adjust your custom field value.

As the preferences are stored at the custom field level

Will those updates reflect in each person’s individual preferences in their account settings? I’ll try it out and see. Thanks for the help 🫡 🐝

Yes that's correct.

if you have more than 1 selection for the field, you can use Value 1||Value 2||Value 3 to store that information to start with

when I try to make an automation it only allows me to assign one of the values from my custom field. how would i go about assigning all of them?
